If high carbon steel is quenched for hardening in a bath, it becomes extra hard, extra brittle and has unequal distribution internal stresses and strain and hence unequal harness and toughness in structure. As a result of hardening, the hardness and wear resistance of steel are improved. Although martensite is the hardest form of steel, it is also the most brittle, thus making it unsuitable for most applications. Special attention is paid to hardness, tough-ness and dimensional stability. this is part one of a two part video on the heat treatment of steels that explores the theory behind different types of heat treatments. Steels are particularly suitable for heat treatment, Heat treatmentis defined as an operation involving the heating and cooling of a metal or an alloy in the solid-state to obtain certain desirable properties without change composition.
